There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.
Post 2. @Anon91339: A ricer is also a legitimate kitchen tool. You can find references to ricers online, or in any culinary dictionary. My mother used to use a ricer to squeeze pulp from seeds when making plum jam.There are photos online. Ricers as kitchen tools predate automobile Ricers and probably the automobile itself.ost 2. @Anon91339: A ricer is also a legitimate kitchen tool.

The potato ricer was in common use long before a version was patented, making it difficult to state an exact date of invention. Several types of potato ricer exist, each wit â¦ h it's own patent date and applications.The earliest patent for a device called a 'potato ricer' was US Patent #1,885,873, issued on November 1, 1932. This doesn't mean it was the first potato ricer, just an improvement on an earlier version.In Mrs. Norton's Rocky Mountain Cook Book Third Edition published in 1918 (first published in 1903 by Caroline Trask Norton of Denver Colorado), a potato ricer is mentioned.he inventor of the original best orange peeler is a man by the name of Wilbur Blank. He invented the peeler back in 1938 when he was 19, out of a love for oranges but a dista â¦ ste for peeling them by hand. He called it the QWIK ORANGE PEEL.
